Scientists from the University of Manchester have shown for the first time that magnetic clouds in graphene can be controllably dissipated and then condensed back, allowing researchers to work towards transistor-like devices in which information is written down by switching graphene between its magnetic and non-magnetic states. In a report published in Nature Communications, a [...]

In a newly published study, researchers from the Argonne National Laboratory detail how they seemingly defied the laws of physics, using hydrostatic pressure to make dense materials with interpenetrated atomic frameworks into novel porous materials. Lemont, Illinois – When you squeeze something, it gets smaller. Unless you’re at Argonne National Laboratory. At the suburban Chicago [...]

In a newly published study, researchers from SLAC National Accelerator Laboratory proved that the magnetism in the LaAlO3/SrTiO3 heterostructure comes from the titanium atom. Scientists from SLAC and Stanford have used finely tuned X-rays at the Stanford Synchrotron Radiation Lightsource (SSRL) to pin down the source of a mysterious magnetism that appears when two materials [...]

In a new study, SLAC and Stanford scientists detail a new three-layer solid-state device can directly identify the wavelength of light that hits it. Researchers at SLAC and Stanford have created a new device, smaller than a grain of rice, that could streamline optical data communications. It can directly identify the wavelength of light that [...]

By coating electrodes made of silicon with a conducting polymer hydrogel, researchers developed a new technique to significantly improve the charge storage capacity of lithium-ion batteries. Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy substance similar to the material [...]

Using a new a printing process called FLUENCE (fluid-enhanced crystal engineering), researchers have developed highly aligned single-crystalline organic semiconductor thin films that are capable of conducting electricity 10 times more efficiently than those created using conventional methods. Menlo Park, California — Through innovations to a printing process, researchers have made major improvements to organic electronics—a [...]

A new study from Columbia Engineering researchers reports on the strength of large-area graphene films grown using chemical vapor deposition (CVD), correcting the mistaken consensus that grain boundaries of graphene are weak. In a new study, published in Science May 31, 2013, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small [...]

A new resin material that can be molded into highly conductive 3-D structures shows potential for making customized electrodes for fuel cells, batteries and biosensor interfaces for medical uses. Washington, May 29, 2013 — Though its surface has been turned to carbon, the bunny-like features can still be easily observed with a microscope. This rabbit [...]

Researchers look to improve magnetic memory by controlling spin orientation in magnetic nanodisks. “We spent 15 percent of home energy on gadgets in 2009, and we’re buying more gadgets all the time,” says Peter Fischer of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Fischer lets you know right away that while [...]

Researchers at UC Davis have developed a new fabric that works like human skin, forming excess sweat into droplets that drain away by themselves. A new water-repellent fabric, stitched with water-carrying threads, can take up and drain liquid such as sweat emerging from the skin. Videography by Siyuan Xing/UC Davis Waterproof fabrics that whisk away [...]

An international team of researchers used a method called atomic-scale multilayer sputtering to create iron-platinum alloys with an ordered crystal structure that could be used for the next generation of hard drives. Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material [...]

Researchers at the Berkeley Lab have developed the first fully integrated nanosystem for artificial photosynthesis. In the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable energy sources has been achieved. Scientists with [...]
